1. On Multistage Analysis of Transonic Compressors: From Axisymmetric Throughflow Time-Marching to Unsteady Three-Dimensional Methods
Sammanfattning : A throughflow time-marching finite-volume solver, capable of computing viscous transonic multistage compressor flows with embedded shocks, is presented. The behavior of the blade model, based on the blade mean surface flow tangency condition, was investigated for transonic flows. LÄS MER
2. The Axisymmetric Turbulent Wake
Sammanfattning : This thesis presents a theoretical and experimental study of the turbulent axisymmetric wake. In the theoretical part, an equilibrium similarity solution of the far wake was derived that was found to admit to two different solutions for this flow. LÄS MER
3. The Axisymmetric Turbulent Jet
Sammanfattning : This thesis aims at understanding the downstream evolution of the most energetic features of a turbulent axisymmetric jet. The study was conducted from 2 to 69 diameters downstream, using 3 different jet exit diameters with air flowing at a wide range of velocities to ensure a reasonable span of Reynolds numbers, while still keeping it in a high range, from 40,000 to 156,700.

4. Multipole moments of axisymmetric spacetimes
Sammanfattning : In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion. LÄS MER
5. Estimation of hydrophobicity of insulating surfaces by studying sessile water drops
Sammanfattning : Today, the traditional insulator materials for high voltage powerlines, i.e. glass and porcelain, are gradually being replaced with new materials, most notably silicone rubber. LÄS MER
